 Once the trees were removed. Light could get to the area below the long branches. 

What was struggling to survive was three rose bushes.

The first one was in the worst shape 

I was hoping that cutting it back to what looked like it was alive and feeding the plant, then just maybe.

After a few weeks

It was alive and sending off new growth.

Now, to bring you up to date

So many questions.  What will the roses be like?
